What methods are used to sanitize or sterilized needles?

Needles can be sanitized or sterilized using several methods. Common techniques include autoclaving, which uses steam under pressure to kill microorganisms, and chemical sterilization with agents like ethylene oxide. Additionally, needles can be disinfected with alcohol or other antiseptic solutions to reduce contamination risk before use. However, it’s important to note that single-use needles are typically preferred in medical settings to ensure safety and prevent infection.
